Abstract
The accuracy of collinear adjustment in traditional satellite altimeter data processing affects the final solution accuracy.Aiming at the problem that gross error may still exist after preliminary processing of the satellite altimetry data,this paper puts forward an algorithm fusing robust and collinear rank-defect adjustment.The proposed algorithm combines advantages of traditional collinear adjustment and robust estimation,retains the excellent properties that rank-defect free network adjustment doesn't need control points,effectively eliminates gross error existing in the rank-defect free network,and finally achieves more accurate calculation results.Experimental result shows that the calculation precision of the proposed algorithm in this paper is higher when compared with the traditional collinear rank-defect adjustment algorithm.关键词
